Replace text

i have a text file with 100 lines


for example:

aa,45,78,79,80,81,82,83,84,85,86,88,14
ab,22,80,99,56,84,85,86,89,12
ac,11,78,79,80,81,82,83,84,16,72,94,5,7,14
ad,58,78,79,80,81,82,83,84,85,86,88,14


i want to replace all de 45,51,78,80,90
45 = A1,A11
51 = A2,A22
78 = A3,A33
80 = A4,A44
90 = A5,A55

but maybe need to be more than 5 could be 5 or more


Output

aa,A1,A11,A2,79,A4,A44,81,82,83,84,85,86,88,14
ab,22,80,99,56,84,85,86,89,12
ac,11,A3,A33,79,A4,A44,81,82,83,84,16,72,94,5,7,14
ad,58,A3,A33,79,A4,A44,81,82,83,84,85,86,88,14
